Its normally on the back of the motor on the passenger side. My a/c guy has to reach his hand a good ways down into the motor to get to it so yours might be the same...

OK After reading and looking some said it was a green cap some said a blue cap some said it was up front some said it was on the fire wall.. so the answer is , Its a blue cap and you cannot see it it !! look directly in the BACK of engine in the center , look all the way down you will see 2 aluminium large line , reach your hand down and follow the line it will curve around a bit and you feel it!! but wont see it it .. just unscrew and plug the refill line .. Have an Awesome day ! 2003 Grand Am 6 cylinder!
